I know this issue has so many variables, but I need some ideas in what could be the issue.
I got in my Pana Twin MP-92 supergun. Everything works perfectly with normal arcade boards. I've been using it every day without issues. I wanted to use the Mahjong panel on the supergun, so I wired up a Mahjong board harness. I checked continuity multiple times and my harness checks out. It's wired 100% correctly for Mahjong boards and the Pana fingerboard pinout. I got in a Taisen Hot Gimmick PCB, hooked everything up, and get no picture. I get sound, controls work, but no picture via RGB out. The supergun has an S-Video out, so I plugged that into my PVM and that gave me video, showing the board is fully working. I swapped back to RGB via SCART to BNC, and again, no video.
I double checked my voltages on +5v and +12v, they're sitting at 5.08v and 11.92v. I'm getting 3.77v on the sync line from the PCB. Again, the pinout has been continuity checked multiple times. The supergun has multiple video adjustments, including a sync adjustment. I've tried them all and nothing effects the issue.
Any ideas guys?
Thanks.
